Project description:Coding and long non-coding RNA metabolism is now revealing its crucial role in Amyotrophic Lateral Sclerosis (ALS) pathogenesis. In this work, we performed Illumina RNA-seq analysis on Peripheral Blood Mononuclear Cells (PBMCs) from Sporadic and mutated ALS patients (mutations in FUS, TARDBP, SOD1, C9Orf72 and VCP genes) and healthy controls. Our aim is the whole-transcriptome characterization of PBMCs content, both in terms of coding and non coding RNAs, in order to compare the disease state to the healthy controls, both for sporadic patients and for mutated patients. Out dataset is a starting point for the omni-comprehensive analysis of coding and long non coding RNAs, from an easy to withdraw, manage and store tissue that shows to be a suitable model for RNA profiling in ALS.
Project description:Transcripional profiling of lymphocytes from patients with amyotrophic lateral sclerosis (ALS) (n=11) and healthy control subjects (n=11). The goal was to determine disease response expression signatures relevant of ALS pathogenesis that affect brain and spinal cord. The reference design was used: each Cy5-labeled cRNA sample from ALS patient or healthy control subject was cohybridized on Agilent-014850 Whole Human Genome Microarray 4x44K G4112F with the reference pool formed with equal amounts of Cy3-labeled cRNAs from each sample from the healthy control group. Eleven lymphocyte samples from definite sporadic ALS patients and eleven samples from healthy control subjects were used.
Project description:Sjögren's syndrome is an autoimmune disease manifesting primarily as dryness of eyes and mouth. In this study, we compared gene expression in PBMCs between age- and gender-matched patients with Sjögren's syndrome (diagnosed by ACR criteria) and healthy controls. Cells were collected in heparinized tubes and PBMCs were prepared using Ficoll.

Project description:Comprehensively compare the transcriptional difference in PPD stimulated PBMCs from individuals with different tuberculosis infectious status: tuberculosis patients, latent infectious individuals and healthy controls using the microarray analysis. Two-condition experiment, PBMCs vs. PPD-PBMCs. 12 individuals: 4 TB patients, 4 latent infectious individuals and 4 healthy controls.

In this study, we compared gene expression in PBMCs between age- and gender-matched patients with Sjögren's syndrome (diagnosed by ACR criteria) and healthy controls. Cells were collected in heparinized tubes and PBMCs were prepared using Ficoll. Eleven patients with Sjögren's syndrome and 16 healthy controls were analyzed for expression of TRIM21, IRF1, IRF2, IRF4 and IRF8.

Project description:Despite the discovery of many genetic risk factors, the cause of the motor neuron death that drives terminal pathology in Amyotrophic Lateral Sclerosis (ALS) remains unknown. We report that the skeletal muscle of ALS patients secretes exosomal vesicles that are specifically toxic to motor neurons. This could not be attributed to a trivial down-stream consequence of muscle denervation. In a study of muscle biopsies and biopsy-derived denervation-naïve differentiated muscle stem cells (myotubes) from 67 human subjects, including healthy and disease controls, ALS myotubes had a consistent signature of disrupted exosome biogenesis and RNA-processing, and their exosomes induced shortened, less branched, neurites, greater death, and disrupted localization of RNA and RNA-processing proteins in motor neurons. Toxicity was dependent on presence of the FUS protein, which is highly expressed in recipient motor neurons. As part of this work, we carried out gene expression analysis of myotubes (differentiated myoblasts) comparing ALS against two other motor neuron disorders as disease controls (SBMA, Spinal and bulbar muscular atrophy; and Spinal Muscular Atrophy Type 4, SMA-IV) and healthy controls.
Project description:Transcriptional profiling of human PBMCs comparing healthy controls, patients with diabetic nephropathy and patients with ESRD. PBMCs were analyzed as they mediate inflammatory injury. Goal was to determine effects of increasing severity of diabetic nephropathy on global PBMC gene expression. Microarray analysis of PBMCs taken from patients with varying degrees of diabetic nephropathy.
